+.B netmask \fI<n>
+Set the interface netmask to <n>, a 32 bit netmask in "decimal dot"
+notation (e.g. 255.255.255.0). If this option is given, the value
+specified is ORed with the default netmask. The default netmask is
+chosen based on the negotiated remote IP address; it is the
+appropriate network mask for the class of the remote IP address, ORed
+with the netmasks for any non point-to-point network interfaces in the
+system which are on the same network.
+.TP
+.B noaccomp
+Disable Address/Control compression in both directions (send and
+receive).
+.TP
+.B nobsdcomp
+Disables BSD-Compress compression; \fBpppd\fR will not request or
+agree to compress packets using the BSD-Compress scheme.
+.TP
+.B noccp
+Disable CCP (Compression Control Protocol) negotiation. This option
+should only be required if the peer is buggy and gets confused by
+requests from
+.I pppd
+for CCP negotiation.
+.TP
+.B nocrtscts
+Disable hardware flow control (i.e. RTS/CTS) on the serial port. If
+neither the \fBcrtscts\fR nor the \fB\-crtscts\fR option is given,
+the hardware flow control setting for the serial port is left
+unchanged.
+.TP
+.B nodefaultroute
+Disable the \fBdefaultroute\fR option. The system administrator who
+wishes to prevent users from creating default routes with \fIpppd\fR
+can do so by placing this option in the /etc/ppp/options file.
+.TP
+.B nodeflate
+Disables Deflate compression; \fBpppd\fR will not request or agree to
+compress packets using the Deflate scheme.
+.TP
+.B nodetach
+Don't detach from the controlling terminal. Without this option, if a
+serial device other than the terminal on the standard input is
+specified,
+.I pppd
+will fork to become a background process.
+.TP
+.B noip
+Disable IPCP negotiation and IP communication. This option should
+only be required if the peer is buggy and gets confused by requests
+from
+.I pppd
+for IPCP negotiation.
